You’ll have absolutely no chance with the auto trans. Do the Z3’s even have the aftermarket internals available to handle that?
The K24Z3’s in all the TSX’s had the 11:1 comp ratio. The 10.5 was in the accords.I read up on the the auto / manual and this 2010 k24z3 has highest compression ratio 11:1 when the later model has 10:5.1 engine compression ratio.
